STARCHING-MACHINE.

Application filed. February 26, 1912.

To all whom it may concern:

Be it known that 1, MICHAEL MANCoLD, a subject of the German Emperor, and resident of Munich, in the Kingdom of Bavaria, Germany, have invented new and useful Improvements in Starching -Machines, of which the following is a specification.

Starching machines in which the clothes to be starched are laid on a rubbing surface having transverse corrugations and treated with the starch thereon by means of fluted rollers reciprocating thereover, are already known. These machines are, however, of a very primitive form and by no means admit of a convenient introduction and removal of the clothes.

The present invention relates to a starching machine in which the upper rubbing surface can be lifted off the lower grill-like rubbing surface, said upper rubbing surface being connected to the top a which top is vertically guided upon rods a? projecting upwardly from the tank a and operable by aid of a foot lever. The two rubbing surfaces are, according to the present invention moved in opposite directions to each other, so as to obtain as intense and rapid an action as possible.

In the accompanying drawings Figure 1 is a side elevation; Fig. 2 a front elevation of the machine closed down. Fig. 3 is a vertical section on the line AB in Fig. 5. Fig. 4 shows the upper roller, its bearing and the housing for the gears partly in section. Fig. 4 is a sectional view taken on line 45 P of Fig. 4.. Fig. 5 is a plan view of the machine. Fig. 6 is a sectional detail view of the device for applying pressure to the roller for pressing the upper rubber against the lower rubber. Fig. 7 is a detail view showing the locking device fdr locking the top to the tank. Fig. 8 is a detailed sectional view through a portion of the upper cover on line 88 of Fig. 3.

As evident from the drawings, and in particular from Fig. 3, the machine consists essentially of a fiat tank or container at, in which the lower rubber b is reciprocated on rollers by means of a double-armed lever cl fulcrumed at f and an eccentric e. The lower rubber b is made according to the present invention of rods arranged beside and parallel to each other in form of a grate or grill. To the frame carrying this grill are attached agitating webs 0, which will Specification of Letters Patent.

continuously agitate the starch and prevent its settling. ()ver the fiat tank a is fitted, according to the present invention, a top a moving in vertical guides in such a manner, that it may be lifted from the tank a and lowered down on the same when pressure is removed from or exerted on the foot lever 12 fulcrumed in the lower part of the machine between the legs and coupled with the top a by means of rods 0, 0. In this top a is fitted in suitable manner the upper rubber 6 having a transversely corrugated rubbing surface. Reciprocating movement may be imparted to the upper rubber b by a rod 21 pivotally connected with said rubber at one end and having its other end engaging a slot in the upper end of the lever d. The rubber b is provided with studs 5 engaging a guiding element a carried by the top a to insure reciprocation of the rubber b in a straight line of travel to raise the rubber and also permit of its downward adjustment by the roller 9. In the tank a is furthermore arranged above the rubber b apressure device consisting of a screw spindle h and a resilient roller g. This device will allow of pressing the upper rubber at a variable pressure against the lower rubber, and thereby rubbing the starch more or less intimately into the clothes, as may be required The top a may be locked in its position lowered on to the tank a by any suitable means, the locking devices Z being connected to a lever m arranged easily accessible from in front, so that by a pressure on the lever the locking devices will be operated to lock or unlock the top. On the front edge of the top at is furthermore provided a roller 70 made of india rubber or the like and situated above a second roller 70 mounted at the edge of the tank in such a manner, that these rollers will prevent the portion of clothing not to be starched to come into contact with the starch. The lower roller 70 may be coupled with the shaft carrying the eccentric e in the manner shown in Figs. 4 and 5 by means of a pair of bevel gears, of which one may be fitted with a free-wheel ball clutch, so that on this shaft being revolved in a reverse direction, for instance, by means of the belt drive shown in Fig. 5 having one fast and two loose pulleys, the lower roller 70 will be revolved. The piece of clothing will then be drawn out between the rollers 70 and 70 and at the same time the starch will be wrung out.

Behind the top a a container 1' is provided preferably attached to the body of the machine, and containing an agitator; in this container the starch is stirred. From this container the starch is then supplied to the piece of clothing to be starched.

As shown in Figs. a and 1- the vertically reciprocating top (1, carries above the ends \V of the shaft for the upper roller 71: square casings G into which extend from above adjusting screws S carrying a collar D. The ends W of these shafts are surrounded by rings R each carrying at its top a bolt B having its top shaped so as to form a collar D. Between the collar D and the bottom part of the casing a spring F is inserted and a spring F is inserted between the collars D and D.

If the cover a is raised or lowered by means of a foot lever n the upper roller 70 will participate in the movement of the cover as it is carried along by the collar D. If the screw S is screwed deeper into the casing G the spring F exerts a pressure upon the bolt 13 by means of which the ring R and with the same the roller is is pressed against the lower roller 70 The ring 17 for the end W of the shaft of the lower roller is is secured. by means of a flap L to the side of the tank a.

X is the protecting casing for the gears .T and T.

As may be seen from Fig. 8 the studs Z2 are slotted and are guided by means of these slots on the horizontal rod a. This will enable the rods to have a slight vertical play in the vertical movement of the cover M.

I claim:

A starching machine comprising in combination a starch container, a lower rubber a movable top, a roller and an upper rubber carried by said movable top, a roller mounted on said container mechanism for driving said container roller and reciprocating both of said rubbers irrespective of the position of adjustment of said top and its rubber, and means for lowering the top to bring the top roller into coacting relation with said container roller, substantially as described.

In testimony whereof I ailiX my signature in presence of two witnesses.

MICHAEL MANGOLD.
